    摘要: Disclosed herein are processes for preparing an α,ω-Cn-diol, wherein n is 5 or greater, from a feedstock comprising a Cn oxygenate. In one embodiment, the process comprises contacting the feedstock with hydrogen gas in the presence of a catalyst comprising Pt, Cu, Ni, Pd, Pt, Rh, Ir, Ru, or Fe on a WO3 or WOx support. In one embodiment, the process comprises contacting the feedstock with hydrogen in the presence of a catalyst comprising a metal M1 and a metal M2 or an oxide of M2, and optionally a support. In one embodiment, M1 is Pd, Pt, or Ir; and M2 is Mo, W, V, Mn, Re, Zr, Ni, Cu, Zn, Cr, Ge, Sn, Ti, Au, or Co. The Cn oxygenate may be obtained from a biorenewable resource.

    摘要: Furfural is produced by contacting a feedstock solution containing C5 sugar and/or C6 sugar with a solid acid catalyst using reactive distillation. Both high yield and high conversion are obtained, without production of insoluble char in the reaction vessel. Degradation of furfural is minimized by its low residence time in contact with the solid acid catalyst. Higher catalyst lifetime can be achieved because the catalyst is continually washed with the refluxing aqueous solution and not sitting in high-boiling byproducts like humins, which are known to be deleterious to catalyst lifetime.

    摘要: Powders such as pigmentary titanium dioxide (TiO2) often demonstrate poor bulk handling properties. It is very cohesive, often dusty, and many grades have loose bulk densities that are lower than desired by customers for their processes. The present invention relates to a process for manufacturing low-dusting, smoothly-discharging, easily dispersible, powders such as pigmentary titanium dioxide that resist compaction, aging, lumping, and/or caking. Particularly, the present invention relates to a process for treating powders such as pigmentary titanium dioxide with ammonia or a similarly basic substance prior to or during agglomeration to produce a powder with improved bulk handling properties. The present invention also relates to powders treated as such, including titanium dioxide.
